Swimmers Valerie Grand'Maison of Fleurimont, Que., and Brianna Nelson of Calgary both won silver medals along with wheelchair sprinter Brent Lakatos of Dorval, Que.

Grand'Maison won her second silver of the Games in the S13 100-metre freestyle for visually impaired. The world record holder and defending Paralympic champ, finished in 1:00.07, just behind American Rebecca Anne Meyers of the U.S.

"It wasn't the race I was hoping for," Grand'Maison said. "I tried a strategy because she has a better first length and I wanted to keep pace with her. The second length was my time to shine and I wasn't able to finish. Perhaps I wanted it too much and made errors. I gave everything I had mentally and physically."

In the women's S7 200m individual medley, Nelson was runner-up to Jacqueline Freney of Australia. It was her second silver of the competition.

Lakatos took silver in the men's T53 wheelchair 400-metres, finishing in 50.71 seconds.

"The last 100 metres hurt a lot, my arms were burning," he said. "A silver medal means a lot."

Canada has now won 11 medals in London to sit 15th in the overall standings. Swimmers and track athletes have accounted for all the medals.
